HRV Showcase

Use this page when you need a deterministic high-vs-low HRV pair behind the published RMSSD, SDNN, pNN50, and lnRMSSD figures.

This page uses hrv_high and hrv_low as the canonical pair for explaining how accepted RR intervals become successive RR differences and then the short-term time-domain HRV metrics surfaced by the app. The framing is aligned to the short-term HRV guidance summarized by Shaffer and Ginsberg (2017), while remaining explicit that this repository publishes short-term RR-derived telemetry rather than clinical 24 h norms.

Computation Path

AcceptedRrSamples
-> AdjacentRrDeltas
-> CurrentRmssdMs / SdnnMs / Pnn50Percent / LnRmssd
  • Hrv.Diagnostics.AcceptedRrSamples exposes the RR window accepted by the tracker.
  • Hrv.Diagnostics.AdjacentRrDeltas exposes the beat-to-beat delta series used by RMSSD and the related time-domain solves.
  • Hrv.Telemetry.CurrentRmssdMs, SdnnMs, Pnn50Percent, and LnRmssd expose the final documentation values shown in the figure.

Interpretation Notes

  • The tracker uses accepted RR intervals rather than a clinically edited Holter NN series, so the figures should be described as short-term RR-derived telemetry.
  • ln(RMSSD) is included because many papers report the log-transformed form to reduce skew and improve comparability across sessions.

Showcase Preset

The showcase-v1 preset keeps the HRV tracker on a deterministic 120 s window with a 32-sample minimum so the exported figures stay reproducible and still map cleanly onto the longer-window operator guidance in the main workflow docs.
